[SOLVED] ldconfig is breaking symlink for amd drivers

Hello! In May I made a post talking about any pacman operation breaking symlink in my /usr/lib folder. Awesome people guided me to solution it but I think we missed something. (https://bbs.archlinux.org/viewtopic.php?id=296223)
I want to start off by saying that after any pacman operation in terminal I see these two lines:

ldconfig: /usr/lib32/libdrm_amdgpu.so.1 is not a symbolic link

ldconfig: /usr/lib/libdrm_amdgpu.so.1 is not a symbolic link

They're printed before ":: Running post-transaction hooks...", but they did nothing
Today however after running pacman -Syu and rebooting sddm failed to load, I checked my /usr/lib again, and found out that symlink was broken once again.
I did not find a wiki page on ldconfig, nor does my system have a man page on it. So I searched the internet and found that ldconfig stores it's configuration data in /etc/ld.so.conf, or in my case it includes /etc/ld.so.conf.d/*. There were a few files:

>cd /etc/ld.so.conf.d
>for file in *; do
echo "\n$file"
cat "$file"
done

hip-runtime-amd.conf
/opt/rocm/hip/lib

lib32-glibc.conf
/usr/lib32

rocm.conf
/opt/rocm/lib

No mention of amdgpu. Then I found that ldconfig has cache.

>ldconfig -p | grep amdgpu
	libomptarget.rtl.amdgpu.so.18.1 (libc6,x86-64) => /usr/lib/libomptarget.rtl.amdgpu.so.18.1
	libomptarget.rtl.amdgpu.so (libc6,x86-64) => /usr/lib/libomptarget.rtl.amdgpu.so
	libdrm_amdgpu.so.1 (libc6,x86-64) => /usr/lib/libdrm_amdgpu.so.1
	libdrm_amdgpu.so.1 (libc6) => /usr/lib32/libdrm_amdgpu.so.1
	libdrm_amdgpu.so (libc6,x86-64) => /usr/lib/libdrm_amdgpu.so
	libdrm_amdgpu.so (libc6) => /usr/lib32/libdrm_amdgpu.so

Verbose mode prints more info:

>ldconfig -v | grep amdgpu
ldconfig: Can't stat /opt/rocm/hip/lib: No such file or directory
ldconfig: Path `/usr/lib64' given more than once
(from <builtin>:0 and <builtin>:0)
ldconfig: Can't stat /usr/libx32: No such file or directory
ldconfig: /usr/lib32/libdrm_amdgpu.so.1 is not a symbolic link

	libdrm_amdgpu.so.1 -> libdrm_amdpro.so.1.0.0
	libomptarget.rtl.amdgpu.so.18.1 -> libomptarget.rtl.amdgpu.so.18.1
ldconfig: /usr/lib/libdrm_amdgpu.so.1 is not a symbolic link

	libdrm_amdgpu.so.1 -> libdrm_amdpro.so.1.0.0
ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied

Sadly I can't find where to configure ldconfig so it doesn't break my symlink. Any help would be greatly appreciated

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

What does `pacman -Qikk libdrm` give you?

Edit: Ok, I read the previous thread, it looks like you have amdgpu pro for some reason? Why, and how did you set it up?

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

Hello! Thank you for your reply

looks like you have amdgpu pro for some reason? Why, and how did you set it up?

I tried to install proprietary driver because I had some issues in minecraft, they're fixed long ago, and I don't need driver anymore.
I used this page https://wiki.archlinux.org/title/AMDGPU … stallation as a guide and installed amdgpu-pro-oglp from aur. Here's pacman log from that day if it is relevant:

[2024-05-15T18:23:50+0300] [PACMAN] Running 'pacman -U --config /etc/pacman.conf -- /home/ilia21/.cache/yay/amdgpu-pro-installer/amdgpu-pro-oglp-23.40_1741713-1-x86_64.pkg.tar.zst'
[2024-05-15T18:23:51+0300] [ALPM] transaction started
[2024-05-15T18:23:51+0300] [ALPM] installed amdgpu-pro-oglp (23.40_1741713-1)
[2024-05-15T18:23:51+0300] [ALPM] transaction completed
[2024-05-15T18:23:51+0300] [ALPM] running '30-systemd-update.hook'...
[2024-05-15T18:23:51+0300] [PACMAN] Running 'pacman -D --asexplicit -q --config /etc/pacman.conf -- amdgpu-pro-oglp'

Right now this package is deleted and I use open source drivers

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

How about `pacman -Qo /usr/lib/*amdpro*`?

❯ pacman -Qo /usr/lib/*amdpro*
error: No package owns /usr/lib/libdrm_amdpro.so.1
error: No package owns /usr/lib/libdrm_amdpro.so.1.0.0

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

Those files shouldn't be there, especially untracked. I would suggest running lostfiles and clean up the system.

But for the current problem, I'm guessing deleting those and reinstalling libdrm will take care of it.

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

Thank you for quick reply. I renamed them by adding .bak to each file, I also did the same for the files in /usr/lib32. Reinstalled libdrm, (by running it with -S, there are a lot of dependencies, and  I can't delete it) and I'm still getting this:

ldconfig: /usr/lib32/libdrm_amdgpu.so.1 is not a symbolic link

Edit:
looks like my symlinks in /usr/lib broke again:

❯ ls /usr/lib32/ | grep amdpro
libdrm_amdpro.so.1.0.0.bak
❯ ls /usr/lib/ | grep amdpro
libdrm_amdgpu.so.1 -> libdrm_amdpro.so.1.0.0.bak
libdrm_amdpro.so.1.0.0.bak
❯ ls /usr/lib/libdrm_amdgpu*
 /usr/lib/libdrm_amdgpu.so -> libdrm_amdgpu.so.1
 /usr/lib/libdrm_amdgpu.so.1 -> libdrm_amdpro.so.1.0.0.bak
 /usr/lib/libdrm_amdgpu.so.1.123.0

I will relink manually right now, but posting just in case it is relevant

Nobody said to rename them in place.

Re: [SOLVED] ldconfig is breaking symlink for amd drivers

I'm so sorry for not listening to your instruction. Deleting them solved the issue, thank you, very much.
I did this just so I can restore them if something breaks.
Once again sorry and thank you for helping me.
